[0042] It can be understood that the excavation equipment provided by the embodiment of the utility model is provided with a lifting support assembly 310 of the dust removal device 300 on the second operating carrier 200, and a water curtain assembly 320 of the dust removal device 300 is provided at one end of the lifting support assembly 310 away from the second operating carrier 200. The length of the lifting support assembly 310 is suitable for telescopic, and a first telescopic control member 313 is provided on the lifting support assembly 310, and the first telescopic control member 313 is provided on the cab 110. When the main body 100 of the equipment moves, the two operating carriers 200 are synchronously driven to move, and the dust removal device 300 moves with the two operating carriers 200 to change positions, which can save the manual movement of the water curtain assembly 320. When the main body 100 of the equipment is arranged in place, the operator in the cab 110 can control the lifting and lowering of the lifting support assembly 310 through the first telescopic control member 313, so that the water curtain assembly 320 is raised to a position less than or equal to 100 mm from the top plate, and then open the water curtain assembly 320 to achieve the purpose of dust reduction. During this process, there is no need for manual operation to raise and lower the water curtain assembly 320, which can save labor costs and improve the safety of the operation.

[0045] Among them, when the lifting support assembly 310 includes a pneumatic telescopic rod 311, the first telescopic control component 313 can be a pneumatic valve, which is used to control the compressed gas or air in the pneumatic telescopic rod 311 to be discharged from the pneumatic cylinder body, so that the piston rod of the pneumatic telescopic rod 311 is retracted, thereby lowering the water curtain assembly 320; the pneumatic valve is also used to control the compressed gas or air of the external equipment to enter the pneumatic cylinder body, so that the piston rod of the pneumatic telescopic rod 311 is extended, thereby raising the water curtain assembly 320.

[0046] In addition to the pneumatic telescopic rod 311, the lifting support assembly 310 can also be a gas spring, a hydraulic cylinder or a mechanical combination structure.

[0049] Since the second telescopic control component 314 is arranged in linkage with the first telescopic control component 313, when the second telescopic control component 314 is controlled to operate to raise or lower the water curtain assembly 320, it is equivalent to operating the first telescopic control component 313 to raise or lower the water curtain assembly 320, that is, operating the first telescopic control component 313 or the second telescopic control component 314 can raise or lower the water curtain assembly 320, but the control positions are different to adapt to use in different scenarios.

[0050] Continue reading Figure 1 and Figure 2 In some embodiments of the present invention, the water curtain assembly 320 includes a water curtain spray pipe 321 , an air supply pipeline 322 and a water supply pipeline 323 .

That is, when the dust concentration is greater than the preset concentration, the controller controls the air control component 324 and the water control component 325 to open, so as to form a water curtain at the injection port 3211 of the water curtain injection pipe 321 for dust removal.
